Despite the obvious pervyness in this game, this is actually a really good rail-shooter similar to games like House of the Dead or Time Crisis where you have to take down various enemies with different difficulties and bosses that are also challenging and fun.

I quite love the stories for the different romance options in the game, including the possible sister route which is a lot of fun as is Aoi's true ending where she attains her dream that you helped her reach!

I would recommend this more on a discount for those interested and it's a lot of fun for multiple playthroughs.

The only downside is, as of writing this review there has been a bug where it sometimes crashes (usually when in big picture) and it has yet to fixed in this regard.
